Real-time cdma2000 personality

(Option 201, ESG-DP and ESG-D series only)

Description

Option 201, cdma2000 personality, adds a flexible solution for
cdma2000 mobile and base station test to Agilent Technologies
ESG-D and ESG-DP (high spectral purity) series RF signal genera-
tors. Option 201 is a firmware personality that requires Option
UN8, (hardware revision C or greater), real-time baseband genera-
tor to be installed in the ESG. The fully coded nature of this solu-
tion in both forward and reverse mode supports long and short
codes, cyclic redundancy checks, convolutional or turbo encoding,
interleaving, power control, and complex scrambling. Additional
capabilities allow flexible channel configurations with individually
adjustable power levels and data rates, customizable user data,
and variable chip rates. The option is backwards compatible with
IS–95A, in both the base station and mobile simulation modes,
through support of radio configuration 1 and 2.
